Configure and deploy load balancers (HAProxy, AWS ELB/ALB/NLB) for distributing traffic, session management, and high availability.

Includes scriptsDevOps & Cloud

AI-generated overview

Configures and deploys load balancers such as HAProxy and AWS ELB/ALB/NLB for traffic distribution and high availability.

What it does: Provides guidance and reference material for deploying and configuring load balancers, including HAProxy configuration, AWS Application Load Balancer CloudFormation templates, health check scripting, and monitoring. It covers traffic distribution across backend servers, session persistence, SSL/TLS termination, and failover. It also ships a validation script and an API scaffold template.
When to use it: Use it when setting up multi-server traffic distribution, high availability and failover, sticky sessions, health checking, or SSL/TLS termination. It also fits cross-region balancing, load-balancer-level rate limiting, and DDoS mitigation planning.
Requirements: Runs in an agent that can read the bundled reference documents and templates. It ships an executable script (scripts/validate-api.sh) and a template (templates/api-scaffold.yaml). Deploying to AWS or running HAProxy requires the corresponding infrastructure, tooling, and credentials.

Overview

Deploy and configure load balancers to distribute traffic across multiple backend servers, ensuring high availability, fault tolerance, and optimal resource utilization across your infrastructure.

When to Use

Multi-server traffic distribution
High availability and failover
Session persistence and sticky sessions
Health checking and auto-recovery
SSL/TLS termination
Cross-region load balancing
API rate limiting at load balancer
DDoS mitigation

Quick Start

Minimal working example:

conf

# /etc/haproxy/haproxy.cfgglobal    log stdout local0    log stdout local1 notice    maxconn 4096    daemon
    # Security    tune.ssl.default-dh-param 2048    ssl-default-bind-ciphers ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256    ssl-default-bind-options ssl-min-ver TLSv1.2
defaults    log global    mode http    option httplog    option denylogin    option forwardfor    option http-server-close
    # Timeouts    timeout connect 5000    timeout client 50000    timeout server 50000
// ... (see reference guides for full implementation)

Best Practices

✅ DO

Implement health checks
Use connection pooling
Enable session persistence when needed
Monitor load balancer metrics
Implement rate limiting
Use multiple availability zones
Enable SSL/TLS termination
Implement graceful connection draining

❌ DON'T

Allow single point of failure
Skip health check configuration
Mix HTTP and HTTPS without redirect
Ignore backend server limits
Over-provision without monitoring
Cache sensitive responses
Use default security groups
Neglect backup load balancers
